There are many discrepancies on the maps. USGS maps will show a trail one place, Google Street Maps will show something different, and the Google Satellite photo will show it somewhere else. The USGS map says
Alta Peak is 11,204’, but the contour lines clearly show that it is 11,280’+. Despite the new measurements on Whitney, the USGS GNIS database still says 14,494’. The “summits” of Mt. Morrison and Mt. Lamarck are lower than nearby un-named summits.
To add to the confusion, I’m working on climbing the Sierra Club SPS list. I’ve been recording my summits for 30 years, and I needed a way to combine my database (just a giant text file) with the official SPS list to produce a new list showing which SPS peaks I have and haven’t climbed. To make that work, I had to change my recorded elevations to match the elevations in the SPS list. That included changing Whitney to 14,491’.
